This invention relates to an improved spring wheel and the objectthereof is to provide a simply constructedand eflicient wheel of thisclass provided with .a flexible rim or channel resiliently connectedwith the hub and means for limiting the yieldability of the wheel.

lVith the foregoing and other objects in rim or channel taken on theline 44 of Fig. 1. v

In the embodiment illustrated, awheel 1 is shown having a hub 2 providedat one end with an integral plate 3 and at its other end with aremovable plate 4 secured in position by means of a nut 5 secured to theouter end of the hub for locking the variousparts of the wheel inassembled position. A socket member 6 is keyed to the hub 2 midway theends thereof and is provided with a plurality of radially extendingslots 7 to receive I spring spokes 8 which are made in'the form of platesprings and have one end thereof arranged in the slots 7 of the socketmember 6' and their other end detachably connectied escribed. The hubmember 6 and the springs 8 are provided on opposite sides withregistering grooves or notches 9 and 10 which form annular channels onopposite sides of the hub member to receive annular ribs 11 and 12formed on the inner faces of washthe breakage of the springs.

ere/13 and 14 whereby the springs and socket member are locked together.

A channeled rim 15 is mounted on the outer ends of the springs 8 and iscomposed of a plurality of pivotally connected sec-' tions, as 16,provided with laterally spaced inwardly extending flanges 18 and 19. Oneend 16 of each section fits inside the adjacent end 16 of the other andis oifset and overlapped by said end 16 as is clearly shown in Figs. 1,2 and 4 and by means of which-dirt is prevented from working into the.interior of the wheel. These segmental sections 16 are provided neartheir periph cry or outer edges with shoulders, as 17 which, when theparts are assembled, form a continuous shoulder around the outer facesof the wheel which are adapted to be engaged by the periphery of thecasing plates hereinafter descrlbed to limit the inward movement ofthese rim sections to-prevent Springs 8 extend between the flanges 1.8and 19 and are connected with the rivets, as 20, which connect thesections. The free ends of these springs are provided with eyes, as 21,through which the rivets 20 are designed to pass to hold them inoperative position. The sections 16 are also provided with laterallyspaced longitudinally extending outwardly projecting flanges 22 and 23to form a seat for the tire 24 which .is preferably made of hard rubber.

Plates 25 and 26 are provided with central apertures adapted to fit overthe hub 2 on opposite sides of the wheel and are clamped between theplates 4 and 3, and the washers 13 and 14, respectively, the outer freeedges of said plates extending on opposite sides of the flanges 1.8 and19 of the rim sections to provide guides for said flanges and the edgesof which are adapted to engage the shoulders 17, as hereinbeforedescribed, to limit the inward movement of said rim sections relativelyto said plates.

It will thus be evident, when it is desired to remove a spring 8 for anyreason, all that is necessary is to unscrew the nut 5 and remove theplate 4 from the hub and the plate 25 whereby a spring may be readily detached by slipping out the rivet which conmeets its outer end to the rimand a new spring maybe inserted Without removing the rubber tire orseparating any of the other parts of the wheel.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the invention,will be readily understood Without requiring a more extendedexplanation. Various changes in the form, proportion and the minordetails of construction may be resorted to without departing from theprinciple or sacrificing any of the advantages of the invention, asdefined in the appended claims.

Having thus described my invention, what I claim is:

A spring wheel comprising-a channeled rim composed of a plurality ofsegmental sections, each having flanges extending in v wardly from itsopposite edges, shouldersarranged onthe outer faces of said flanges, oneend of one section overlapping the. ad-

ebstee jacent end of the adjacent section, a pivot extendingtransversely through said overlapping portions, a hub, plate springsconnected at one end to said pivots and at their other end to the hub,and a tirearranged in flanges and stops for limiting the inward movementof the rim sections.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
